WATER-COLUMN.

Specification of Letters Patent.

Patented May 19, 1914.

Application filed July 2, 1912. Serial No. 707,401.

To all whom it may concern 7 Be it known that I, ABRAM VAN Bnonr, a citizen of the United States, and a resident of Bridgeport, county of F airfield, and

tate of Connecticut, have invented certain new and useful Improvements in v ater- Columns, of which the following is a specifi gasket between the front of the glass, and the front member of the watercolumn, this packing or gasket being of only one piece.

Another object of my invention is to provide an improved form of packing member or gasket, between the rear of the glass, and the removable frame member, that will permit free circulation of the water through the device, at the rear of the glass,'and that will also freely admit of expansion and contraction of the glass.

WVith these objects in View, the invention will be hereinafter more particularly described with reference to the accompanying drawings, which form a part of this specifi cation.

In the accompanying drawings illustrating my invention, Figure 1. is a front View of the water column; Fig. 2, is a vertical section on the line AA of Fig. 1; Fig. 3, is a rear elevation of the device; Fig. 4, is a section view of the pipes on the line D--D of Fig. 2; Figs. 5, 6, 7, 8, 9 are views and sections of the removable frame member forming a part of the water column; Fig. 10, is a view of the dowel pin, used in connection with the removable frame member; Fig. 11, is a transverse section on the line BB, Figs. 2, 3; Fig. 12, is a plan view of an adjusting screw; and Fig. 13, a plan view of one of the bolts used to fasten the front mem ber t0 the back member or casing of the device.

2 represents an elongated body of the casing of the water column which is formed of one integral casting having a longitudinal pocket therein, and is further provided with holes in its upper and lower ends to receive the pipe connections 16 and 16 respectively. Suitable ribs 28 and 28 are formed on the sides of the body to strengthen the same. The front plate 1 is provided with a central longitudinal sight opening 21 and further includes a marginal portion 30, against which the glass3 is placed with its interposed gasket 5, the latter of which is of one piece, and extends across the fiat back surface of the front member 1. The front member 1, is provided with bosses 8, through which the bolts 22, pass and help to strengthen the said member, when the n1emher is bolted and fastened to the flange 26 of the casing 2. These bolts areprovided all around the front opening of the casing, to make a water tight joint at the front marginal edges of the casing.

The frame member 4, Figs. 5, 6, 7, 8, 9, which is to be inserted from the front of the body, is formed a little smaller than the openingin the body, and is provided with an elongated cavity 15 into which the steam and water have free access. This frame is placed on the dowel pins 77, which are arranged in holes formed inside of the casing to keep the body member in its proper position.

A gasket 6, is placed between the frame 4, and the glass 3, and is formed of suitable shape and size, to correspond with the face 31, of the frame member 4, as shown in Fig. 5.

The cavity 15, is to provide a space for the water, and 2323, are passages for the circulation of the water, at the back of the glass, 3. The water passes through the openings 2020, in the pipes 1616', to which are attached the connections of another vessel; the pipes are threaded at their ends 17-17 in the usual manner, and have the fiat portions 19 for the use of a wrench.

The glass 3, is clamped between the gasket 5, pressing against the marginal flange 30 of the opening 21, in front member 1. A packing member 6, is pressed against the back 25, of the glass 3, by the frame member 4, the latter being secured in position by the adjusting screws 9, passing through and having threads 12 to engage the back of the easing 2, and being further provided with packing nuts 10, and packing 11.

The front opening of the casing being closed by the front member 1, and the glass 3, the bolts 22, may be taken out, and the glass 3, and the frame member 4, with the gasket 6, can be removed by drawing them.

forward through the opening in the casin thus permitting the parts to be removed and replaced. It will further be seen that it will not be necessary to remove the frame member 4, when it is desired to remove or replace the glass 3, in this water-column.

I am aware that prior to my invention, water-columns have been made with a front member in conjunction with a glass. I therefore do not claim such a combination broadly; but

I claim 1. In a water column of the class described, the combination of an elongated integral body having a pocket therein and holes in its ends, a removable front closure plate secured thereto and having a central longitudinal sight opening therethrough and having an inner flat surface, a fiat gasket covering the flat surface of the closure plate and arranged in part against the body, a transparent closure fitted over the sight opening and against the inner edge portion of said gasket, an integral elongated frame member arranged Within the casing and having a cavity therein and a steam inlet and outlet in line with the holes in the body, and a series of adjustingscrews fitted through the integral or solid back portion of the body to engage the frame to set the same against the transparent member.

2'. In a water column of the class described, the combination of an elongated integral body having a pocket therein and holes in its ends, a removable front closure plate secured thereto and having a central longitudinal sight openingtherethroi'igh and having an inner flat surface, a transparent closure fitted over the sight opening, an integral elongated frame member arranged Within the casing and having a cavity therein and a steam inlet and outlet in line with the holes in the body, a series of pins fitted in both the body and the frame to support the latter, and a series of adjusting screws to engage the frame to set the same against the transparent member.

3. In a water column of the class described, the combination of an integral body having an elongated pocket therein and holes in its ends, a rei'novable front closure plate secured thereto and having a central longitudinal sight opening therein and hav ing an inner fiat surface, a transparent closure fitted against said fiat surface of the closure plate and a gasket intermediate of said closure plate and the body and between the front surface of said closure plate and the transparent closure, the edge portion of said transparent plate being free from engagement with any of said parts to permit of contraction and expansion, an integral elongated frame nember arranged within the casing and having an elongated cavity therein open against the transparent closure and having a steam inlet and outlet in line with the holes in the body, a gasket arranged between the said frame and the transparent member, and a series of adjusting screws mounted in the body and engaging the frame to set the same against the transparent member.

This specification signed and witnessed this first day of July A. D. 1912.
